If you've called, faxed, and written yourself silly and you still can't reach the Herald, try Mike's at lunchtime: You may find that writer who's been avoiding you. The café, located on the ninth floor of the Venetia condominium, serves tasty and affordable meals that are like catnip to the scribes and editors barricaded across the street in One Herald Plaza. It may only be an urban myth, but it is believed that at least two Herald employees are eating at Mike's at all times. Who can blame them? Hot roast beef-cheddar sandwiches, broiled grouper, shrimp scampi: The food is better than expected and priced to move. The waitresses are nice, too. True story: The editors of Tropic spent so many afternoons on the outdoor patio that their magazine folded from neglect.
